Transport Safety (see figure F)
The transport safety-lock 24 enables easier han-
dling of the machine when transporting to vari-
ous working locations.
Releasing the Machine (Working Position)
– Push the tool arm by the handle 2 down a lit-
tle in order to relieve the transport safety-
lock 24.
– Pull the transport safety-lock 24 completely
outward.
– Guide the tool arm slowly upward.
Note: When working, pay attention that the
transport safety-lock is not pushed inwards.
Otherwise, the tool arm cannot be lowered to
the requested depth.
Securing the Machine (Transport Position)
– Press lever 1 and at the same time, swing the
tool arm by handle 2 toward the rear until the
transport safety-lock 24 can be pushed com-
pletely inward.
The tool arm is now securely locked for trans-
port.
Mounting the Extension Bars
(see figure G)
Long workpieces must be underlaid or support-
ed at their free end.
To extend the saw table additionally, extension
bars can be mounted both to the left or right of
the power tool.
– Insert the extension bars 38 on both sides of
the power tool to the stop in the drill holes
16 intended for this purpose.
– Tighten the screws for securing the exten-
sion bars.
Clamping the Workpiece (see figure H)
To ensure optimum working safety, the work-
piece must always be firmly clamped.
Do not saw workpieces that are too small to
clamp.
– Press the workpiece firmly against the
fence 5.
– Insert the material clamp 17 provided into
one of the holes 14 intended for it.
– Loosen the wing bolt 39 and adapt the mate-
rial clamp to the workpiece. Tighten the wing
bolt again.
– Firmly clamp the workpiece by turning the
threaded rod 40 in clockwise direction.
Loosening the Workpiece
– To release the material clamp, turn the
threaded rod 40 in anticlockwise direction.
Adjusting the Cutting Angle
f Before any work on the machine itself, pull
the mains plug.
To ensure precise cuts, the basic adjustment of
the machine must be checked and adjusted as
necessary after intensive use (see “Checking
and Adjusting the Basic Adjustment”, page 38).
f
Always tighten the locking knob 8 firmly be-
fore sawing. Otherwise the saw blade can
become wedged in the workpiece.
Adjusting Horizontal Mitre Angles
(see figure I)
The horizontal mitre angle can be set in the
range from 47° (left side) to 47° (right side).
– Loosen the locking knob 8 in case it is tight-
ened.
– Pull the lever 9 and turn the saw table 6 until
the desired mitre angle is indicated on the
angle indicator 10.
– Tighten the locking knob 8 again.
